[OpenLayers-Users] how to make simultanous wms calls in open layers

[Ravi Pavuluri]

Andreas,

I apologise for replying in this thread. I will create a new thread if that is 
more appropriate. 


I had a similar issue as Imran and tried doing the way you mentioned. It works 
faster. But I see a higher number of httpd threads in Apache eating away my RAM. 
I am using geoserver as my web mapping server and have the following values in 
Apache configuration.

MinSpareServers 5
MaxSpareServers 10

Is this an expected behavior? and is there some way to counter this?
I had a similar problem when using TileCache with mod_python and not mod_cgi. Am 
I missing something in common in Apache?

Thanks,
Ravi.

Hey,

most browsers only do a small amount (~4) of requests to a single domain at the 
same time. If you want more tiles to be loaded in parallel, use more than one 
URLs, e.g.

http://tiles1.myhost.org/
http://tiles2.myhost.org/
http://tiles2.myhost.org/

They can all point to the same server.

Regards,
Andreas.
